The invention discloses a continuous pipe resistant to H2S corrosion and a manufacturing method thereof. The continuous pipe comprises following material by mass percent such as C of 0.03-0.06 %, Si less than or equal to 0.152 %, Mn of 0.15-0.55%, P less than or equal to 0.01, S less than or equal to 0.003, Cr of 0.2-0.6 %, Mo less than or equal to 0.02, Ni of 0.1-0.27%, V of less than or equal to 0.06%, Ti of less than or equal to 0.03%, Nb of 0.05-0.09%, and the balance Fe. The continuous pipe resistant to H2S corrosion helps to solve the problem that an existing steel continuous pipe loses efficacy at a quick pace in an acid environment.The low-carbon low-manganese continuous pipe resistant to H2S corrosion has great intensity, plasticity and corrosion resistance.While meeting the mechanical properties of tubular products in the first place, banded segregation of parent material is substantially reduced by the low-carbon low-manganese alloying composition design so that defects are effectively reduced and H collection is prevented. The formation and expansion of cracks do not easily occur so that corrosion resistance of tubular products is remarkably improved. In the meantime, residual stress of tubular products by optimizing weld seams and carrying out thermal processing technology of parent material so that corrosion resistance is further enhanced.
